摘要

了解种质间的性状变异规律和种质间的性状特征对作物改良具有重要意义。以2018年和2019年21份苋菜种质为研究对象，研究了不同种质间的基因型多样性程度及其性状特征。对数据进行方差分析、相关分析和主成分分析。以茎重(SWT)为产量，采用品种×产量性状组合(GYT)双标图对各品种的性状进行分析。大部分性状的加入、年份和加入×年均方差均显著(P≤0.05/0.01)。前3个主成分解释了88.18%的可观测变异，其中株高(PHT)、单株叶数(NOL)和根重(RWT)是主要贡献因子。SWT与NOL、TBM、RWT呈显著相关(P≤0.01)。编号NGB00019和NGB00061与包含所考虑的所有YT组合的扇区相关。而NGB00019是产量与其他性状的最佳组合。进一步的研究应涉及更多的性状，以确定剩余材料的性状特征。

Genetic diversity and trait profiles of some Amaranthus genotypes

Knowledge of the pattern of trait variation among accessions, and the trait profiles of the accessions is crucial for improvement of a crop. Twenty-one Amaranthus accessions were evaluated in 2018 and 2019 to investigate the extent of genotypic diversity among the amaranth accessions and their trait profiles. Data were subjected to analysis of variance, and correlation and principal component analyses. Taking stem weight (SWT) as the yield, the accession × yield-trait combination (GYT) biplot was employed to investigate the trait profiles of the accessions. Accession, year, and accession × year mean squares were significant (P≤0.05/0.01) for most of the measured traits. The first three principal components explained 88.18% of observable variation among the accessions and identified plant height (PHT), number of leaves per plant (NOL), and root weight (RWT) as the major contributors. Significant (P≤0.01) correlation was observed in the association of SWT with NOL, TBM, and RWT. Accessions NGB00019 and NGB00061 were associated with the sector containing all the YT combinations considered. However, NGB00019 was identified as the best combiner of yield with other traits. Further studies involving more traits should determine the trait profiles of the remaining accessions.

期刊介绍： Advances in Horticultural Science aims to provide a forum for original investigations in horticulture, viticulture and oliviculture. The journal publishes fully refereed papers which cover applied and theoretical approaches to the most recent studies of all areas of horticulture - fruit growing, vegetable growing, viticulture, floriculture, medicinal plants, ornamental gardening, garden and landscape architecture, in temperate, subtropical and tropical regions. Papers on horticultural aspects of agronomic, breeding, biotechnology, entomology, irrigation and plant stress physiology, plant nutrition, plant protection, plant pathology, and pre and post harvest physiology, are also welcomed. The journal scope is the promotion of a sustainable increase of the quantity and quality of horticultural products and the transfer of the new knowledge in the field. Papers should report original research, should be methodologically sound and of relevance to the international scientific community. AHS publishes three types of manuscripts: Full-length - short note - review papers. Papers are published in English.
